How to calloutputpanel by another outputpanel command button.

1. I have two radio button, once page will load then one will select default and one empty datascroller table will display with four column and two button in below the table. ex. AddGroup button and Preview Button
2. once user will click on add group button then current two button will hide and same datascroller table should display with same button now Ui will show two datascroller table.
3. If user will click once again on AddGroup button then Same Datascroller table should display. Like that it will keep on call based on user requirment.

Now i am able to display one table while page is loading. In that i have created two button also. But while click on button how to call data scroller table with same no of column (4 column)
